Something Need To Know For The Best DIY Purchase

When choosing the band saw, for example DIY, you need to have some basic knowledge about this machine. As a fact, there have 2 kinds of band saws with 2 or 3 wheels. For the first time of purchase, the 3-wheel band saw can be highly recommended rather than the other. By simply reading in the website bandsawsexpert.com or refer here to both get the wanted things when making a decision about the band saw.

The Shortcoming Of 3-Wheel Band Saw

There still have some disadvantages of 3-wheel band saw. With this category, the blade of the 3-wheel machine will change its direction 3 times in 1 revolution, thereby making an increase in wear and causing the breaking of premature of the blade owing to the hard work. Also, the wheels are pretty smaller, which makes the blade change in a tighter circle and repeat again will cause the break in premature blade because of metal fatigue. The wheels with smaller diameter may give less contact area for the drive, which may lead to slippage during the heavier cutting process. And due to the pretty small wheel, the effect of flywheel will be lost and no run-on itself. As a result, this will make the band saw easily stall.

Outstanding Feature Of 2-Wheel Band Saw

Unlike 3-wheel, with 2 wheels band saw, the blade only turns its direction twice, and the longevity of the blade will be 1/3 longer compared to 3-wheel model. The larger wheel will create the effect of flywheel and give more drive on the surface area. As a principle of thumb, the longer band saw will operate after being switched of the better to enable the ability of keep-going. However, you should take into serious consideration that some kind of larger band saw will have the break to finish the blade when being turned off the power. Remember the disadvantage of 2-wheel band saw is that it has pretty fewer throats.

Motors

The core reason a wood turner purchases a band saw is to cut surrounding turning blanks and rip down the billets. In which, the ripping may require the horsepower. With less than 1hp band saw, it may struggle against the green hard blanks of wood. For the better, you should come up with the machine with more than 1 hp if possible. In addition, some kind of band saw will have a variety of pulleys to let different ratios. This has a positive impact on increasing the power of the machine; however, it is in the expense of limiting speed.

Cutting Height

The measurement of this distance is from the table upwards of the band saw to the top guide when being extended fully. And this will decide the size of the blank that you are going to cut. For a wood turner, the minimum bare should be 6 inches (150mm). but, with less than 1hp motor, it seems to be impossible to cut 6’’ blanks.

Blade Guides And Rollers

This is quite essential part of the band saw, which consists of 2 reactions of cutting. If the blade is let to move farther rearward, it will fall off the driving wheel. Each movement is counter acted along with guides and races of ball bearing, below, and above the cutting area. The movement of backward blade is normally countered with a ball bearing, which permits the blade of band saw to rub on, and can prevent the friction, by rotating bearing. If the bearing is smaller, it can rotate quicker and wear out quicker.

Blade

The medium wood turner is basically either cutting circles or ripping down for turning blanks. It is suggested to be the best for the course cutting blades. The blades of band saw are classed with the imperial measure. Teeth are divided into the point per inch (PPI), teeth per inch (TPI), watch diagram for clarification. Among 3 kinds, TPI is the most popular method in NZ. As a principle of thumb 3TPI, it would be good for the wood turner. It can deal with green wood as well as carry out of the sawdust without extra clogging.
